My real surname isn't weird, just really bog standard for round here. So I usually write under fake names (two, mainly) but unaccountably worked on one book using my real surname - not even sure why. Last week, I was hate-watching a YT video made by some nutters who seem to have it in for me (or her, the person I write as). And they started bitching about me when I was working using part of my real surname - only done it once. I have the same surname as a character in 'Red Dwarf' (NO! Not Rimmer!) And on the playback of the Live Chat, as these dicks started talking about my book, and I was waiting for some heavy duty insults coming my way but one of their regular trolls said "...OH X, like X in Red Dwarf?" and I thought "Really? Is that the best you can do?" It's not even a character I mind being likened to. In fact, it's my favourite.
In their other (hobby related) YTs they have spent months slagging off one of my Reddit usernames, not even realising it's the same person as the person whose work they also slag off... There's also an Instagram feed where the same people hate me both on Reddit and my work pseudonym IRL - which I follow with great interest. They still haven't joined the dots. If one of the British ones doxes me I'm down the coppers, though.
